Answer:
1.25 m
Explanation:
This is the vertical height not the distance along the slope.
![K=U\\\frac{1}{2}mv^{2} = mgh\\h = \frac{v^{2}}{2g}=\frac{25}{20}=1.25 m](https://tex.z-dn.net/?f=K%3DU%5C%5C%5Cfrac%7B1%7D%7B2%7Dmv%5E%7B2%7D%20%3D%20mgh%5C%5Ch%20%3D%20%5Cfrac%7Bv%5E%7B2%7D%7D%7B2g%7D%3D%5Cfrac%7B25%7D%7B20%7D%3D1.25%20m)
Answer:
Explanation:
heat lost by coffee = heat gain by aluminum spoon
heat lost by coffee = mc ( 85° C - T)
175 ml of water = 175 grams
175 grams = (175 / 1000) kg = 0.175 kg
heat loss by coffee = 0.175 × 4182 J/Kgk ( 85 - T) = 731.85 ( 85-T) = 62207.25 - 731.85 T
heat gain by aluminum spoon = 0.012kg × 897 J/kgK ( T - 22) = 10.764 T - 236.808
10.764 T - 236.808 = 62207.25 - 731.85 T
10.764 T + 731.85 T = 62207.25 + 236.808
T = 84.086 ° C approx 84°C
